RankGuru · Accepted Answer

An **Adiabatic Process** is defined as one in which there is no heat exchange between the system and its surroundings.
- **Condition**: $q = 0$
- This typically happens when the system is perfectly insulated or if the process occurs so rapidly that heat has no time to flow.
- From the first law: $\Delta U = q - w \implies \Delta U = -w$.
- If the gas expands ($w > 0$), its internal energy and temperature must decrease.
